<span>The answer is Haploid spores germinate to give rise to protonema, which later develops into a sporophyte.</span>
A protonema (plural: protonemata) is a
thread-like chain of cells that forms the earliest stage (the haploid phase) of a bryophyte life
cycle..
<span>A haploid gametophyte ( each of whose cells contains a fixed number of
unpaired </span>chromosomes)  gives rise to a <span>diploid sporophyte</span>,.
Gametophytes produce haploid sperm and eggs which fuse to form diploid zygotes
that grow into sporophytes. 
 
        
             
        
        
        
There are three ways in which exogenous dna can be
introduced into a bacterial genome. These are; transduction, transformation and
conjugation. Transduction is the introduction of exogenous material into bacteria
by viruses; conjugation is exchange of genetic material between bacteria sexual
through  reproduction; while transformation
is uptake of exogenous dna by bacteria, from its surrounding, through the
bacterial membrane.
